The antenna includes a first electrode, a second electrode, a third electrode, and a photodielectric variable layer. The first electrode and the second electrode are respectively disposed on opposite two sides of the photodielectric variable layer. The first electrode includes a plurality of transmission electrodes, and the plurality of transmission electrodes are configured to transmit an electrical signal. The second electrode is provided with a fixed potential. The third electrode includes a plurality of radiator units, and the plurality of radiator units are configured to send the electrical signal. The antenna further includes at least one light-emitting element configured to emit light irradiated to the photodielectric variable layer to change a dielectric constant of the photodielectric variable layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna and preparation method thereof, phase shifter and communication device","description":"Provided are an antenna and a preparation method thereof, a phase shifter, and a communication device.
